S3 Upload Integration Drift

cluster-29

AWS SDK/runtime mismatches and trigger/timing differences cause S3 uploads to fail or behave non-deterministically after server-side or library changes, leaving “works for me” symptoms that vanish only after pinning versions, removing layers, or switching to EventBridge.

INSTANCE_OFProblem

Need to deploy a multi-file GitHub repository to AWS Lambda

INSTANCE_OFProblem

trying to get an object from my S3 bucket using pre-signed URLs. Tension: I've tried encoding the slashes `%2f` with no change. Outcome: upgrade to the latest SDK, in your case boto3.

INSTANCE_OFProblem

fails with a 403 Forbidden error and the message CannotVerifyCopySource — I'm trying to copy a CSV file from an AWS S3 bucket to Azure Blob Storage using AzCopy. Tension: The command executes but fails.

INSTANCE_OFProblem

Ceph object gateway returns HTTP 400 on PutObject

INSTANCE_OFProblem

I am using AWS SDK to generate a presigned S3 object URL and sending it as a mail notification. Tension: Even though I am setting the expiration time to 2 days.

INSTANCE_OFProblem

Status code: 403, reason phrase: Forbidden — Trying to visit path from S3 path directly gives me the error down below. Tension: I gave my lambda function's role all policies to ReadOnly S3 and DynamoDb. In S3 object ownership is set to ACLs Disabled. All 5 block public access checkboxes are unchecked. Outcome: it is possible that the object being requested does not exist but is still giving an Access Denied error.

INSTANCE_OFProblem

Unable to inject and configure Aws\S3\S3Client as a Symfony service

INSTANCE_OFProblem

the question is that can I safely remove the task role and replace it with a new role containing the amazonS3FullAccess — I am running a AWS ECS faragate task. Tension: I understand that the task execution role must contain the AmazonECSTaskExecutionRolePolicy to function. Outcome: Yes you can remove `AmazonECSTaskExecutionRolePolicy` from `Task IAM role` and add s3 permissions.

INSTANCE_OFProblem

aws s3 sync and aws s3 cp fail with MissingContentLength / stream is not seekable errors

INSTANCE_OFProblem

The exception happens at build() — S3Client.builder() .region(Region.US_WEST_1) .credentialsProvider(StaticCredentialsProvider.create(awsCredentials)). Tension: java.lang.NoClassDefFoundError: software/amazon/awssdk/http/auth/scheme/NoAuthAuthScheme. Outcome: Adding http-auth-2.30.4.jar to the classpath resolves this issue and the Exception no longer occurs.

INSTANCE_OFProblem

The bucket you are attempting to access must be addressed using the specified endpoint. Tension: Status Code: 301.

INSTANCE_OFProblem

this script run without issues from an IP that is NOT `11.22.33.44`. Tension: the `aws s3 ls` command is indeed blocked (due to the IP restriction, since the user has full `s3` access). Outcome: Creating pre-signed URLs does not hit the AWS API.

INSTANCE_OFProblem

I need to access certain S3 buckets programmatically using IAM Roles Anywhere — working on a Spring Boot backend service. Tension: I’m unsure how to use it to create IAM Roles Anywhere sessions and authenticate to access S3.

INSTANCE_OFProblem

The HTTP request cannot be executed: The peer resets the connection. — When I try to upload files to S3 from storage via an application deployed on the stand. Tension: Everything is working locally. All files is uploading without errors. Outcome: com.amazonaws.SdkClientException exception.

INSTANCE_OFProblem

Uploading to LocalStack S3 from a Quarkus app fails with an UnknownHostException when interacting with the configured S3 endpoint.

INSTANCE_OFProblem

nothing is getting written to the s3 bucket — trying to use ytdl-core in an AWS lambda function to upload an .mp4 of a youtube video to an S3 bucket. Tension: I cannot get ytdl to create a stream with any data in it. Outcome: Right now nothing is getting pushed to the buffer or the s3 bucket.

INSTANCE_OFProblem

Caused by: java.lang.ClassNotFoundException: Class org.apache.hadoop.fs.s3a.S3AFileSystem not found — when I'm running my pod. Outcome: When I add "hadoop-aws" dependency it works.

INSTANCE_OFProblem

Delegation token provider with service name s3-hadoop has multiple implementations

INSTANCE_OFProblem

I keep encountering a SignatureDoesNotMatch error. — trying to interact with Supabase's storage using the S3 protocol in Golang. Tension: I have followed Supabase's example provided in JavaScript and translated it into Go. Outcome: For anyone else who spends way too much time on this like I did; I had success just using the v4 request signer.

INSTANCE_OFProblem

we want to directly call the lambda if the size of request body is small and return response directly from lambda — We have created an AWS API Gateway which is integrated to S3 object put. Tension: keep the above integration if request body is large. Outcome: The integration pattern you were asking for is going to be constrained by the maximum size of API gateway (10MB) and Lambda payloads (6MB).

INSTANCE_OFProblem

Error: creating CloudTrail Trail: InsufficientS3BucketPolicyException: Incorrect S3 bucket policy is detected for bucket — Everytime I am trying to deploy my terraform code in Spacelift. Tension: Incorrect S3 bucket policy is detected for bucket. Outcome: Could you please help me with this?

INSTANCE_OFProblem

understanding the event payload structure passed by EventBridge to my .NET Lambda function — an AWS serverless application using .NET, where I'm configuring a Lambda function to be triggered by S3 events routed through AWS EventBridge. Tension: I'm specifically seeking guidance on understanding the event payload structure passed by EventBridge to my .NET Lambda function and how to process it effectively. Outcome: How can I deserialize and process the event payload within my .NET Lambda function to perform actions based on the S3 event that triggered it?

INSTANCE_OFProblem

requests to the load balancer IP are being redirected to the official page of AWS S3 services — we're considering utilizing Google CDN for serving our AWS S3 bucket. Tension: it's not working as expected; hitting the load balancer IP of Google Cloud should point to the AWS S3 endpoint instead of the official AWS S3 page.

INSTANCE_OFProblem

Setting a custom endpoint for Localstack via environment variable (e.g., AWS_ENDPOINT_URL) causes the AWS CLI to fail with InvalidAccessKeyId during S3 operations, instead of routing requests to Localstack (including STS).

INSTANCE_OFProblem

HTTPClientError: An HTTP Client raised an unhandled exception: sequence item 0: expected str instance, bytes found — save it into a S3 bucket. Tension: My issue is I have added a python `requests` layer which somehow messed with how Lambda send the object to s3 using https. Outcome: The error is gone if I remove the layer.

INSTANCE_OFProblem

Put "https://s3..amazonaws.com/astromail-test3.com": dial tcp: lookup s3..amazonaws.com: no such host — When I switch my credential to default it works correctly and creates the bucket.

INSTANCE_OFProblem

Failed to resolve hostname my-bucket.s3.eu-central-1.amazonaws.com: System error — calling ffmpeg within a child_process.spawn command. Tension: The signed URL is fine. I've tested it with vanilla JS `await fetch(sourceURL)` and it returned the file. Outcome: ffmpeg is callable.

INSTANCE_OFProblem

The AWS Lambda function is not being triggered when new files are uploaded to an S3 bucket. The configured S3 notification is set to respond to HTTP POST events, but no events occur and the code never runs.

INSTANCE_OFProblem

A SageMaker training job launched from GitHub Actions fails to download data from an S3 bucket. The error occurs after starting the TrainingJob with VPC networking configured.

INSTANCE_OFProblem

when I test the Lambda function using the S3-put option. Outcome: This is not the expected result.

INSTANCE_OFProblem

Directly putting objects from user input (`MemoryStream`) to an S3 object storage using Min.IO. Tension: Exception has occurred: CLR/Minio.Exceptions.UnexpectedShortReadException. Outcome: To solve the issue, we have to reset the pointer on our own before passing it to MinIO Client SDK.

INSTANCE_OFProblem

I am trying to attach a policy to an S3 bucket using the AWS CLI with a JSON file containing the policy as input. Tension: My JSON file seems correctly formatted. The first byte is definitely a '{'.

INSTANCE_OFProblem

while creating a bucket with their provided template — aws cloudformation create-stack --stack-name chimesdk-ws-102-s3-cfd --template-body file://csdk-ws-102-s3-cfd.yml. Tension: There is no such thing as `${!RandomDigits 3}` in CloudFormation. Outcome: Your bucket name is incorrect.

INSTANCE_OFProblem

Uploading to S3 via a presigned PUT URL does not apply the desired object tags even when the server-side PutObjectCommand includes the Tagging parameter.

INSTANCE_OFProblem

docs are very sparse — AWS SDK for Swift is still in developer preview. Tension: I want to create a pre-signed URL for an object.

INSTANCE_OFProblem

continuously getting the error: TypeError: Failed To Fetch — I'm using the AWS SDK V3 in my Nextjs application to upload files to s3. Tension: I've previously had this working with no issue but when I changed my secret key on my user today. Outcome: Downgrading to @aws-sdk/client-s3@3.317.0 fixed the issue for me.

INSTANCE_OFProblem

There's an extra array in input of your S3 client instantiation. Tension: I have tried also in sandbox only the library and getting same error. Outcome: Here's the correct syntax:.

INSTANCE_OFProblem

SSL validation failed for https://bucketname.s3.amazonaws.com/ [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate — when loading a file to S3 bucket. Tension: python not able to find certain certificates. Outcome: apply the following parameter when creating the s3 object.

INSTANCE_OFProblem

it throws `oftware.amazon.awssdk.core.exception.SdkClientException: Received an UnknownHostException when attempting to interact with a service.` — I am trying to use software.amazon.awssdk:s3 S3Client to talk to a minio storage. Tension: The hostname was modified as `backend.localhost` in the request.

INSTANCE_OFProblem

Unit tests cannot deterministically simulate S3 upload failure

INSTANCE_OFProblem

Is there a way to not make a S3 bucket encrypted by default or may be remove the added encryption? — Amazon S3 now applies server-side encryption with Amazon S3 managed keys (SSE-S3) as the base level of encryption for every bucket in Amazon S3. Tension: AWS recently changed their policy. Outcome: No. It is not allowed to disable encryption.

INSTANCE_OFProblem

Creating a new folder in an existing bucket displays this message at the top of the AWS S3 Console page every time. Tension: I can't seem to find any answers as to why this is displayed, perhaps its just default no matter the policy setup? Outcome: Just confirmed that the new user interface of S3 bucket now shows this message when creating a folder!

INSTANCE_OFProblem

AmazonS3Exception: The AWS Access Key Id you provided does not exist in our records

INSTANCE_OFProblem

Running `aws s3 ls` without `--profile` returns `AccessDenied` for `ListBuckets`, while `aws s3 ls --profile profile_name` successfully lists buckets. The intent is to make the default behavior use the working profile without specifying it each time.

INSTANCE_OFProblem

Updating an existing CloudFormation stack to set S3 bucket AccessControl: PublicRead fails with AccessControlListNotSupported because the bucket does not allow ACLs.

INSTANCE_OFProblem

Class not found: com.demo.lambda.handlers.DemoHandler: java.lang.ClassNotFoundException — using AWS S3. Outcome: Current classpath: file:/var/task/.

INSTANCE_OFProblem

updating the connection of an s3 bucket, from TLS 1.0 to TLS1.2 — the following connection has been detected: `eu-west-3|bucket| REST.GET.OBJECT|TLSv1|62|[BPImageWalker/2.0 (www.bdbrandprotect.com)]`. Tension: I have been unable to detect where it comes from. Outcome: cloudtrail to detect TLS 1.0 connections and the results are 0.

INSTANCE_OFProblem

Syntax error at or near ':'(line 1, pos 3) — using Minio as my storage and not AWS.
